With 48 V battery line there will remain loads with 12 V. For this reason future cars will have a central DC/DC converter bringing down 48 V to 12 V. Different topologies are possible as for example multiphase coupled and non-coupled inductors. For all topologies Vishay offers a broad portfolio of solutions with standard devices like MOSFETs, Diodes, Resistors, Capacitors and Inductors, as well as with customized magnetic solutions.
